Title: Arc welding
IPC: H05H1/34
Filed: 1974-04-05
Abstract: 1456539 Welding by fusion PHILIPS ELECTRONIC & ASSOCIATED INDUST. RIES Ltd 5 April 1974 [9 April 1973] 15125/74 Heading B3R  In MIG arc-welding, a primary arc between a consumable electrode and a workpiece is struck and maintained in a thermally ionized gas which is provided by maintaining, in a gas flow, an independent secondary arc between two auxiliary non-consumable electrodes, thereby permitting interruption of the primary arc without interruption of the secondary arc to enable a succession of workpieces to be welded without the need for H.F. discharge or short circuit contact between the consumable electrode and the workpiece. As shown, a consumable electrode guide and contact tube 27 and a non-consumable electrode 13 are disposed respectively coaxially with and eccentrically of a constricting orifice 11 of a copper nozzle 9 screwed into a housing 3. A consumable electrode 30 is fed through the tube 27 by rollers 81 driven by a variablespeed motor 83. A complementary non-consumable, annular, copper electrode 21 coaxial with and downstream of the orifice 11, is screwed into a sleeve 19 which is connected, by a nut 17, to the housing and electrically insulated therefrom by an element 25. The non-consumable electrode 13 preferably comprises an end 45, e.g. of tungsten, and a holder 47, e.g. of copper, preferably cooled via coolant connections 49, 51. The housing 3 has an electrically insulating lining 15 and is hollow and provided with coolant connections 35, 37. The sleeve 19 also is hollow, and is provided with coolant connections 41, 43 for cooling of the complementary non- consumable electrode 21. Plasma gas (e.g. inert (e.g. A, He), H, N and mixtures thereof, and possibly oxidizing gases) is fed to at least one port 57 to issue at high speed through the nozzle 9 and electrode 21, and shielding gas (e.g. that for the plasma, and CO 2 , A/CO 2 , A/O, A/He, A/O/CO 2 ) may be fed through ports 59 to issue through the electrode 21. If desired, a further annular shielding gas flow surrounding the electrode 21 may be provided (Fig. 1, not shown). As shown, the non-consumable electrodes 13, 21 are connectible to the poles of a D.C. source 69, via an H.F. generator 67, and the consumable electrode contact tube 27 and the workpiece 73 are connected to the poles of an independent D.C. source 75. The non-consumable electrode 13 and the consumable electrode 30 may be connected to the source positive or, usually, negative poles. Alternatively, the secondary arc may be energized from an A.C. source. The two separate power sources may be housed in one control unit but are separately controllable. In Fig. 3 (not shown), the nozzle 9 is watercooled and insulated from the housing 3 to serve as the complementary non-consumable electrode. In Figs. 4, 5 (not shown), both of the non-consumable electrodes are of rod form and provided within the housing 3 respectively on the same and opposite sides of the contact tube 27.

Title: System for the reliable transmission of data
IPC: H04L1/18
Filed: 1966-04-06
Abstract: 1,146,873. Data transmission systems. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 6 April, 1966 [6 April, 1965], No. 15303/66. Heading H4P. In a system in which digital data is transmitted in blocks, a return error/no error indicating signal being received prior to the transmission of each block, each block includes a multi-bit check word derived by a feedback shift register from the information data. A similar feedback register checks the received blocks. Co-operating stations are identical, their mode of operation at any time being selected by switches controlled by a control unit. At the transmitter the bits transmitted are counted, and after a given number the control unit reads out the check word developed in the register, following which the transmitter is switched to receive. At the receiver a counter fed by the received bits operates the control unit so that only the information bits are passed to the output. The complete block is passed to the register which also feeds the control unit. When a complete block has been counted the control unit passes the output of the register, which indicates whether or not an error has occurred, to a unit which develops an error/no error signal which is returned to the transmitter over the same line as that on which the block was received. This signal passes to the shift register there and, depending on the bit-pattern, causes the transmitter to be switched back to transmission and either to repeat the previous block or to send the next block. If the transmitter receives no signal from the line during a preset period it generates a service signal. It may be arranged that a station acting as receiver may, by sending a special service signal, act as a transmitter of data blocks. A plurality of stations may be interconnected, each station responding only to a particular service signal. A single station may broadcast to a plurality of receivers: in this case only one of the receivers returns an error/no error signal. The other stations each derive an error/no error signal and compare it with that returned by the receiver. If lack of agreement is found by one of these stations it sends a special service signal.

Title: Manufacturing processes using photoresist masks
IPC: G03F1/00
Filed: 1974-04-08
Abstract: 1457924 Photo-resist masks INTERNATIONAL BUSINESS MACHINES CORP 8 April 1974 [3 May 1973] 15432/74 Heading G2X A process using a photo-resist mask comprises (a) forming a photo-resist layer 57 on a substrate 51, 53, 55 (b) exposing parts of the photo-resist layer while varying the exposure energy across the parts to form at least two differently exposed regions 59, 63 having differing solubilities, Fig. 4B (c) developing the resist layer to remove those regions 59 having the highest solubility Fig. 4C (d) treating the exposed substrate e.g. by etching, Fig. 4d, the remaining resist protecting the covered areas (e) developing the resist layer to remove those regions 63 having the next highest solubility Fig. 4E and F treating the exposed substrate e.g. by plating, Fig. 4F the remaining resist protecting the covered areas. The resist can be either negative or positive working and after the final treatment step the remaining resist is stripped off. The varying exposure energy may be formed by exposing the resist through a mask having areas of differing optical density e.g. 0%, 50% and 100% transmission, or through coloured masks or by varying the intensity of a scanning electron beam. The first and second development steps may be carried out with dilute and undilute developer respectively. The resist used is an alkali-soluble positive working resist containing meta-cresol formaldehyde novolak resin (av. mol. wt. 1,000) and a sensitizer which is the 2-diazo-1-oxo-naphthalene-5-sulphonic acid ester of 2, 3, 4-trihydroxy-benzophenone. The process is used for making semi-conductor devices.

Abstract: 1439731 Camera shutters SEIKO KOKI KK 10 April 1974 [11 April 1973] 15890/74 Heading G2A On depressing a shutter release member 3: (1) a switch 21 is closed by a pin 20 on member 3 to energize an electromagnet 32 which then holds a lever 31 to prevent shutter closure. (2) a lever 28, which serves to hold the lever 31 to prevent shutter closure before energization of the electromagnet, is moved to an inoperative position by a pin 27 on member 3. (3) a lever 22 is operated by pin 20 on member 3 to allow the shutter to open. (4) as the shutter opens a lever 35 is released to move to a position in which it prevents return of the holding lever 28 to its holding position on return of the member 3. (5) after a photoelectrically timed period the electromagnet 32 is de-energized to release lever 31 and allow the shutter to close. As shown the shutter comprises an apertured opening blade 7 and an apertured closing blade 8 which when cocked as in Fig.1 are urged leftwards by springs 13, 14. In Fig.4 (not shown), a single non-apertured blade (57) is moved leftwards by a driving wheel (95) to open the shutter and is moved back again by a spring (63) to close the shutter. Preferably the shutter includes a stop member 39 which moves rightwards upon movement of lever 31. Thus if in step (2) the electromagnet is not energized e.g. due to battery failure or insufficient light, lever 31 will move and hence stop member 39 will move to block further movement of release member 3. Similarly at the end of exposure in step (5) stop member 39 moves to block movement of member 3 until the shutter has been re-cocked. The claims of Specification 1439732 are directed mainly towards the stop member 39.
